[0006] As a preferred technical solution of the utility model, the upper part of the needle sleeve body is a bucket-shaped structure, and the lower part of the needle sleeve body is a cylinder-shaped structure.

[0007] As a preferred technical solution of the utility model, the locking assembly includes a positioning and fixing groove provided at the edge of the upper surface of the stab-proof fixing plate, and a plurality of elastic protrusions are staggeredly arranged on the inner walls on both sides of the positioning and fixing groove.

[0008] As a preferred technical solution of the utility model, a suction protrusion is provided at the bottom of the positioning and fixing groove, and a suction and fixing groove cooperating with the suction protrusion is opened on the lower surface of the needle handle.

[0009] As a preferred technical solution of the utility model, a warning sticker is attached to the upper surface of the stab-proof fixing plate.

[0010] As a preferred technical solution of the utility model, two hand positioning grooves are symmetrically arranged on both sides of the lower surface of the stab-proof fixing plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By providing an anti-stab fixing plate and a hand positioning groove in cooperation with two symmetrically arranged inclined guide grooves, it is convenient to put the needle cover back on the needle after blood collection is completed, thereby preventing the medical staff from being stabbed by the needle. By providing an elastic protrusion, an adsorption protrusion and a positioning fixing groove in cooperation with the adsorption fixing groove on the lower surface of the needle handle, it is convenient to fix the needle in the needle cover body, thereby preventing the needle from accidentally detaching from the needle cover body when the needle is recovered, thereby eliminating safety hazards.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] A blood collection needle for preventing stab injuries comprises a needle cover body 3, a detachable needle head 7 is sleeved inside the needle cover body 3, a needle handle 8 is connected to the top of the needle head 7, a blood collection hose 9 is connected to the top of the needle handle 8, an anti-stab injury fixing plate 1 is connected to the top of the needle cover body 3, inclined guide grooves 6 communicating with the needle cover body 3 are respectively provided on both sides of the upper surface of the anti-stab injury fixing plate 1, and a locking component cooperating with the needle handle 8 is provided at the edge position of the upper surface of the anti-stab injury fixing plate 1.
